Abstract
2.5 Gbit/s transmission is demonstrated over a mixed fibre system without using remote optically pumped amplifiers (ROPAs). The use of NRZ data with clock pre-chirp, stimulated Brillouin scattering (SBS) suppression and dispersion compensation enables a +26.5 dBm signal to be launched into fibre. A 980 nm pumped preamplifier with a 3.5 dB noise figure and additional Raman gain at the receiver realises a system length of 392 km with an effective sensitivity of –45.2 dBm. When the system fibre length is increased to 415 km, an error rate is demonstrated which if forward error correction (FEC) were used would give error free transmission.Keywords
